Stereolithography (SLA) / Digital Light Processing (DLP)

In resin technologies, SLA (stereolithography) / DLP (digital light processing), the processed material is a material in the form of a photosensitive resin. The polymerization process is carried out by the laser energy (SLA) or matrix (DLP). Livestock technologies are used in a wide range of applications, e.g. automotive, biotechnology, medicine and jewellery. High precision of parts and a wide range of materials constitute additional advantages of these technologies. Advanced geometry requires support structures. In most cases, they must be removed mechanically. If support structures cause problems in your project, check out SLS.

What are the benefits of SLA / DLP?

Benefity technologii SLA / DLP​

Benefit #1

High precision and smoothness of 3D printed parts

Benefit #2

A wide range of materials

Benefit #3

The possibility of producing parts with high transparency

Benefit #4

Specialized materials intend


Standard resin

The most popular resin, which, due to different manufacturers, is named differently. It provides a good quality/price ratio. Available colors: transparent, white, gray, black.

Contact Your Specialist

Resins imitating the properties of engineering material: ABS-like, PP-like

Resins similar in mechanical properties to ABS and PP.

Contact Your Specialist

Flexible resin

Resin similar in properties to rubber (Shore 80A hardness).

Contact Your Specialist

High-temperature resin

Resin for applications operating at high temperatures (HDT above 200 °C).

Contact Your Specialist

Super clear resin

Material designed for application where high transparency, e.g. flow simulations, is required.

Resin technologies design guidelines

For SLA/DLP technology, we recommend that you follow these recommendations:

Zasady druk 3D

Minimum hole diameter 2 mm

Zasady druk 3D

Minimum wall thickness from 0.6 mm depending on the geometry

Zasady druk 3D

The access to areas with a bottom bracket should be secured in order to remove it

Zasady druk 3D

Positioning pins should be at least 3 mm thick/medium
